BRITTEN, or CHARLOTTE, MICHIGAN, ASSIGNOR o [BRITTEII LIGHT & rowim COMPANY, orLANsINe, MICHIGAN, A CORPORATION or MICHIGAN "RAD O APPARATUS Application filed April- 30,

This invention re lates to improvements in r larly to economize and conserve the current and to regulate and to clarify the tone.

Further objects and objects pertaining to details and economies of construction and operation will definitely appear from the de- 1 scription to follow. 1 p i I accomplish the objects of my invention 1 by the devices and means described in the followingv specification. The invention is clearly defined and pointed out in the claim. A device embodying my invention is clearly illustrated 'in the accompanying drawings forming a part of this specification, in which Fig. 1 is a detail perspective view of my improvement designed as an attachment to an ordinary radio set." v I Fig. 2'is a full size vertical detail longitudinal elevation view partially in section on central plane. I

Fig. 3 is an enlarged detail sectional View on line 3'3 of Fig. 2through the body of the main connectio i Fig. 4: is a detail diagrammatic wiring view" showing the relation of myapparatus in com bination with a radio set. x 1 The parts will be identified by their numerals of reference which are the same in all the views. v a

1 is the base which may be of glass or suitable insulating material. 2 is a metal sup porting column secured to the glass base in any suitable way. 3 is the main connector of my improvedreconomizer and regulator having a horizontal portion 31 disposed in proximity to the base and secured thereto by a suitable welded or soldered button 32. It

has an upright portion and horizontal portion; 33 disposed through the upright supporting;

post 2. This connector comprises an outer tube or casing 34 preferably of copper, an"

Q negative terminal of the said battery cell to inner central wire 35,:arou'nd which isdis posed a coil of wire'36. The coil of-wire is embraced within a layer of mica insulating material 37 The tube is preferably under partial vacuum. Plugs 38 of insulation are in the ends of connector 3. g V

have their ends connected to suitable binding The inner central wire 35 and theccoil 36 posts. The binding post 4 on the lower horii zontal part provides the connection to the 1 radio set 5 containing the usual A, B and C. batteries'and being otherwise organized as.

indicated diagrammatically in Fig. 4.

The binding post 6 is provided with con-' nection 7 leading to-the positive terminal 8' of the battery 9. The negative terminal '11 of the battery 9, which is a 4 volt dry cell battery is connected to the lead 10 to the I i aerial.

The battery 9 is a duplicate of the 0 battery I 0f l ivolt capacity but is not coupled up to act as'a C battery but in the particular auxiliary relation specified herein.

Just how the structure results in the ad-i 1 vantages stated is problematical and appli cant is only able to state the results and define the structure which accomplishes the same is accomplished.

without expanding on the theory by which itv 1 Having thus described my invention, what It I claim as new and desire to secure by Letters "Patent,is: v I The combination with a radio set comprising A, B and G batteries and an aerial of an economizer and clarifying device comprising an auxiliary battery dry cell, a base withv post, a metallic tubular casin with a horizon-' tal lower part and an upright and an upper horizontal partdisposed through said post, a central conductor, a coil of wire around the conductor, the opposite ends of said conductor and coil being connected to a single binding post mounted on the upper and lower ends of the tubular casing which casing is suitably sealed at the ends, a mica insulationbetween the said 0011 and the caslng, a connectlon from It .7 v

the lower binding post to the antenna connection'of the radio set and from the'upper binding post to the positive terminal of said battery dry cell, and a'co'nnection from the p the aerial or antenna of said radio set.

Infwitness whereof I have hereunto set my hand.
